An Uninterruptible Power Supply (UPS) is an electrical apparatus which provides backup power to a load when the normal power source fails. This UPS will provide near instantaneous protection from power interruptions, by using energy that is stored in a battery to substitute the normal supply. This UPS can be supplied either with or without a 7Ah or 9Ah 12V battery (these batteries are the same type used in alarm systems and are available from most electronics stores - easily interchangeable/replaceable if necessary), providing an average of 20 or 30 minutes back-up supply to one PC.

This UPS also provides surge protection - on an unstable power grid, interruptions or load shedding, as well as lightning strikes, can cause spikes which may result in damage to equipment. This UPS has lightning/surge protection up to 175 Joules.

The units are supplied with a power supply cable for the UPS, as well as two cables for supplying equipment with power from the UPS. A legacy RS232 serial cable is also included in the package.

Lead-time of approximately 1-3 days on additional stock, approximately 40 units in stock with supplier.
